A startup that aims to provide flexible options for employer-provided health insurance is making Chicago its home for U.S. operations.

Toronto-based League, which connects workers to a la carte health-care services via an app, has opened shop in WeWork River North, the company announced Tuesday morning.

Founded in 2014 with a focus on small and mid-size companies, League lets employers give their workers a designated amount of cash to use as they choose in League’s digital health marketplace — whether on visits to the doctor or mental health consultations, or on lifestyle services like yoga or massage.

The company also offers access to prescription and hospital benefits, as well as life insurance, long-term and short-term disability.

Through an app or website, employees can find and pay for professional services, get tips from advisers and submit claims.

"We're trying to completely reimagine health benefits and insurance, making it more personalized to their health needs and to push the envelope on redefining the experience," said founder and CEO Mike Serbinis.

Piloted in Canada and Seattle, League has about 116 employees, including about 10 already in Chicago. It plans to add another 25 employees locally by the end of the year, and start doing business in the 10 biggest U.S. markets by summer 2018.

League has about 200 employers as customers, Serbinis said. The company would not comment on revenue.

While League currently has no corporate customers in Chicago, health-care industry talent and a thriving tech startup scene drew the company here, said Serbinis, who previously founded e-book company Kobo.

"Many of those are our customers," he said. "From many standpoints, it just made for a great choice."

Former Blue Cross Blue Shield executive Brian Ancell will lead the U.S. business.

League raised $25 million in Series A funding in June 2016 and began selling its first insurance products in October. Serbinis said it expects to raise about $100 million in the next six to nine months.
